<h1 id="label-Try+Samples">Try Samples</h1>

<p>Let&#39;s try scripts and applications of samples.</p>

<h2 id="label-RubyCocoa+Application">RubyCocoa Application</h2>

<p>First, try to execute a RubyCocoa application which has already been built.
In Finder, open &#39;/Developer/Examples/RubyCocoa&#39; folder and
double-click SimpleApp. Or type following on command line:</p>

<pre class="code ruby"><code class="ruby">% cd /Developer/Examples/RubyCocoa
% open SimpleApp.app</code></pre>

<h2 id="label-on+command+line+-28Terminal-29">on command line (Terminal)</h2>

<p>You can write a script for command line with RubyCocoa. Now, let&#39;s try
to execute a simple script in sample directory.</p>

<pre class="code ruby"><code class="ruby">% cd /Developer/Examples/RubyCocoa
% ruby fontnames.rb # fontname print to stdout.
% ruby sndplay.rb   # system sounds play in order.
% ruby sndplay2.rb  # system sounds play in order with short interval.</code></pre>

<p>For Mac OS X 10.2 or later users, furthermore:</p>

<pre class="code ruby"><code class="ruby">% echo Hello World | ruby speak.rb
% head -5 speak_me.txt | ruby speak.rb</code></pre>

<p>This will be interesting. When you execute speak.rb without arguments, the
Mac will read all the text you type until &#39;control-D&#39; is input.
This script uses the AppleScript (and AppleEvent) interface which has been
implemented since Mac OS X 10.2.</p>

<p>Next, try scripts with windowing.</p>

<pre class="code ruby"><code class="ruby">$ ruby HelloWorld.rb                       # window and buttons
$ ruby TransparentHello.rb                 # transparency!
$ (cd Hakoiri-Musume &amp;&amp; ruby rb_main.rb )  # puzzle game</code></pre>

<h2 id="label-Build+a+Makefile-based+RubyCocoa+application">Build a Makefile-based RubyCocoa application</h2>

<p>The next example is Makefile-based. Type this to build:</p>

<pre class="code ruby"><code class="ruby"><span class='tstring'><span class='tstring_beg'>% </span><span class='tstring_content'>cd</span><span class='tstring_end'> </span></span><span class='op'>/</span><span class='const'>Developer</span><span class='op'>/</span><span class='const'>Examples</span><span class='op'>/</span><span class='const'>RubyCocoa</span><span class='op'>/</span><span class='const'>Hakoiri</span><span class='op'>-</span><span class='const'>Musume</span>
<span class='tstring'><span class='tstring_beg'>% </span><span class='tstring_end'>make</span></span></code></pre>

<p>Now launch the application:</p>

<pre class="code ruby"><code class="ruby">% open CocoHako.app</code></pre>

<p>or double-click &#39;CocoHako&#39; in the Finder.</p>

<h2 id="label-Build+a+Xcode-based+RubyCocoa+application">Build a Xcode-based RubyCocoa application</h2>

<p>The next example is Xcode-based. Type this to build it:</p>

<pre class="code ruby"><code class="ruby">% cd /Developer/Examples/RubyCocoa/simpleapp
% xcodebuild
% open build/SimpleApp.app</code></pre>

<p>You can build and run the application in Xcode, too. Launch the
application:</p>

<h2 id="label-Next...">Next…</h2>

<p>There are various other samples. Please read and try them. Have fun!</p>

<h2 id="label-Supplement">Supplement</h2>
